<h1>October 2013 mod_pagespeed Security Update.</h1>
<h2 id="overview">Overview</h2>
<p>Various versions of mod_pagespeed are subject to critical
cross-site scripting (XSS) vulnerability, CVE-2013-6111. This permits a hostile
third party to execute JavaScript in users' browsers in context of the domain
running mod_pagespeed, which could permit theft of users' cookies or data
on the site. </p>

<p>Because of the severity of the problem, users of affected versions are
<strong>strongly</strong> encouraged to update <strong>immediately</strong>.
</p>

<p>To be notified of further security updates subscribe to the
<a href="mailing-lists#announcements">announcements mailing list</a>.

<h2 id="affected">Affected versions</h2>
<ul>
  <li>Versions earlier than 1.0.</li>
  <li>1.0.22.7 (fixed in 1.0.22.8).</li>
  <li>All 1.1 versions</li>
  <li>1.2.24.1 (fixed in 1.2.24.2)</li>
  <li>1.3.25.1 &ndash; 1.3.25.4 (fixed in 1.3.25.5)</li>
  <li>1.4.26.1 &ndash; 1.4.26.4 (fixed in 1.4.26.5)</li>
  <li>1.5.27.1 &ndash; 1.5.27.3 (fixed in 1.5.27.4)</li>
  <li>1.6.29.1 &ndash; 1.6.29.6 (fixed in 1.6.29.7)</li>
</ul>

<h2 id="solution">Solution</h2>
You can resolve this problem by updating to the latest version of either stable
or beta channels. If for some reason you are unable to update to a new version,
patched versions to resolve the vulnerability are also available for releases
1.0 as well as 1.2 through 1.6.

<h3 id="latest">Upgrading to the latest version</h3>

The easiest way to resolve the vulnerability is to update to the latest
versions on whatever channel (stable or beta) are you currently using.

<p>If you installed the .rpm package, you can update with:
<pre>
sudo yum update
sudo /etc/init.d/httpd restart
</pre>

<p>If you installed the .deb package, you can update with:
<pre>
sudo apt-get update
sudo apt-get upgrade
sudo /etc/init.d/apache2 restart
</pre>

It is also possible to <a href="build_mod_pagespeed_from_source">
build from source. </a>

<h3 id="10">Updating while keeping version 1.0</h3>

On Debian-based systems (including Ubuntu), you can update to the patched 1.0
version by running:
<pre>
sudo apt-get update
sudo apt-get install mod-pagespeed-stable=1.0.22.8-r3546
</pre>

On RPM based systems that use the <code>yum</code> command, you can update
from older versions by using:
<pre>
yum install mod-pagespeed-stable-1.0.22.8
</pre>
<p>Note that this command will not switch you to a lower version number
(for example, it will not switch from a 1.2 version with the vulnerability to
a fixed version of 1.0); it is recommended that you resolve this security
vulnerability by upgrading to the patched release of whatever version you are
currently using, or the latest beta or stable version.</p>
